      Description

      Designed for High-Performance. For serious off-road and other high-performance applications, stock just won’t do. Install the G2 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit and feel the difference! Furthermore, the kit’s gear and pinion are engineered to run cooler and quieter than stock.

      High-Quality Construction. The 8.5 in. & 8.6 in. Rear Ring Gear and Pinion are precisely CNC-machined from forged 8620 steel for exceptional strength and durability. They’re heat-treated for added durability and resistance to harsh environments and extreme use. What's more, the Rear Ring Gear and Pinion are lapped to ensure a smooth finish and reduce friction.

      Professional Installation Recommended. G2 recommends that the kit is installed by a professional mechanic as changing the ring gear and pinion is a complex process. The kit includes installation instructions.

      Backed by 10-Year Limited Warranty. The 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit is warranted to be free of defects in workmanship and materials. Exclusions will apply.

      Application. The G2 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit with 3.08 gear ratio are designed to fit 2007 to 2018 GMC Sierra 1500 models.
